3. CS3011/CS3012 OVERVIEW

The CS301 1/CS3012 amplifiers are de signed for

precision measu rement o f sign als from DC to

1 kHz when opera ting from a supply voltage of

+2.7 V to +6.7 V (± 1.35 to ± 3.35 V). The amplifi-

ers are designed with a patented architecture that

utilizes multiple amplifier stages to yield very high

open loop gain at frequencies of 1 kHz and below.

The amplifiers yield low noise and low offset dr ift

while consuming relatively low supply current . An

increase in noise floor above 1 kHz is the result of

intermediate stages of the amplifier being operated

at very low currents. The amplifiers are intende d

for amplifying small signals with large gains in ap-

plications where the output of the amplifier can be

band-limited to frequencies below 1 kHz.
